Today’s red jungle fowl — the wild forebears of the domesticated chicken — are becoming more chickenlike. New research suggests that a large proportion of the wild fowl’s DNA has been inherited from chickens, and relatively recently. Ongoing interbreeding between the two birds may threaten wild jungle fowl populations’ future, and even hobble humans’ ability […]
SEATTLE — Luke Skywalker’s home planet in Star Wars is the stuff of science fiction. But Tatooine-like planets in orbit around pairs of stars might be our best bet in the search for habitable planets beyond our solar system. Many stars in the universe come in pairs.

UpdateThat 1972 experiment measured the two-way speed of light, or the average speed of […]
Some immune defenses of the brain may have their roots in the gut. A new study in mice finds that immune cells are first trained in the gut to recognize and launch attacks on pathogens, and then migrate to the brain’s surface to protect it, researchers report online November 4 in Nature. These cells were […]
Far too often, fighters say that they can’t afford to lose when they, in fact, can afford to lose. A loss isn't the end for all fighters and the greatest have come back from significant losses in their career. All losses aren't the same and there's often an overreaction to how much a loss hurts […]
